Compare two text files, source codes, or delimited datasets side-by-side or unified with character-level difference highlighting in local memory.
Inspect differences side-by-side with synchronized line gutters, or switch to a unified inline view with standard + and - markers for rapid code review.
Don't waste time hunting for what changed inside a long paragraph or SQL query. Changed characters and tokens are emphasized in darker highlight badges within every modified row.
Zero bytes of your sensitive code, database connection strings, or customer lists ever leave your computer. All diff algorithms run entirely inside your browser memory.
No. All text comparison, diff calculation, and file processing happen 100% locally inside your browser memory. Your confidential code, credentials, and customer datasets never leave your device.
Split (side-by-side) view shows the original document on the left and the modified version on the right with synchronized line numbers. Unified view merges both versions into a single sequential feed with + and - markers, identical to git diff.
Yes! The built-in Delimited List & Set Inspector mode allows you to isolate items only in the original list, items only in the modified list, and common intersection items, with one-click export into the Comma Separator.
When a line has been modified, the tool uses a secondary Longest Common Subsequence (LCS) pass on individual words and characters, highlighting the exact edits in darker red and green pills within the changed line.
